A root canal is necessary when an infection and inflammation are present in the pulp and root of the tooth. The root canal procedure removes the dead or damaged nerve tissue. The tooth is cleaned and sealed. There could be some tender areas after the root canal procedure, however the nerve pain felt before the procedure should improve after the procedure. If you are experiencing pain and have persistent problems with a tooth, call and schedule an appointment with your dentist in Centennial. It is important to get treatment immediately to ensure the problem does not get worse.
